Tags string not translatable

The "Tags" string before showing taxonomy terms applied to the node is not translatable. I fixed it by editing node.tpl.php, changing line 35 from:

<?php if ($terms) { ?><div class="taxonomy"><span>Tags</span> <?php print $terms?></div><?php } ?>

to

<?php if ($terms) { ?><div class="taxonomy"><span><?php print t('Tags') ?></span> <?php print $terms?></div><?php } ?>

Patch is also attached (I hope it works, use above as reference if not).
